is there any way to know this?

yes think a little. the answer is simple. you just have to just sit there and ponder if I was a spamer how could other people find out.......perhaps walk away from the account and then take a second look at the account....... let us know what you find out ...........oh yea hit the thanks button if you get it

It's my personal account so can't just walk away from it.

I dont think there is any way to tell really, just make sure when your adding friends you only do about 100 a day, and have a 30-1min gap in-between adds.

lol

create another account, from different ip, send a request to that account from your suspected account, go to your new account & check where the request is.
